Im sure im doing alot of things wrong, whether it be the tire size and the gearing or what not but, I just havent had that much luck with the radials. But there are other factors which may have caused me not to hook on several runs, including track being to cold, and the track having an oil down and the clean up crew not doing a good job of cleaning it up. But on the streets the tires seem to hook fine but just at the track they just dont hold up well. Im sure switching to a full slick would be better. I dont have a great drag setup, but im working on getting this car to run what it is capable of doing.
